+Weather Underground API integration
+===================================
+
+1. Run the SQL statement again. This is written in such a way that it will only add whatever you don't have.
+
+    `mysql -u root -p weather < CREATE-SP.sql`
+
+2. Add your own values to the settings table.
+
+    ```
+    mysql -u root -p weather -e "update SETTINGS set value='YOUR-STATION-ID' where name='WUNDERGROUND_ID'"
+    mysql -u root -p weather -e "update SETTINGS set value='YOUR-STATION-PASSWORD' where name='WUNDERGROUND_PASSWORD'"
+    ```
+    
+3. Open CRONTAB to configure a recurring task.
+
+    `crontab -e`
+    
+4. Set up a CRON job to automatically send data to Weather Underground every 10 minutes. (Change the URL to match your environment.)
+
+    `*/10 * * * * curl http://localhost/dashboard/wunderground-api.php`
+    
+5. Press `Ctrl O` then `Enter` to save and `Ctrl X` to quit nano.
